Dynamic and efficient routing is one of the key challenges in wireless ad hoc networks. In this paper, based on a reactive AODV protocol, a novel semi-proactive routing protocol, named SP-AODV, is presented that uses proactive routing for some special nodes. The efficiency of the new protocol lies in the fact that some nodes with certain conditions will dynamically update some sections of their routing...
Directed diffusion is a data-centric routing protocol used in wireless sensor networks and uses only local interaction between neighbor nodes. One of the problems of this approach is the mechanism used for routing selection which mostly, leads to select the shortest path between sinks and sources. In this case the nodes in the shortest path will fail after a short period of time due to lack of energy...
One of the most important challenges in mobile ad hoc networks is to use an efficient and dynamic routing protocol, as the nodes can move randomly, which requires the routing protocol to respond quickly to the network topology change. In this paper, a new hybrid routing protocol, based on a reactive AODV routing, is introduced. It follows the proactive approach for some special nodes in some interval...
